Chinese love bones in their food.  I am not just making an observation that there are bones in everything, but, instead, I am relating something that has been told to me by many locals.  In fact, most of my friends will not even eat chicken breast without the bones.  As a western who is not used to having bones in their food, one must be careful.  I have eaten fish, eel, snake, frog, chicken, duck, pork and lamb, at least, all with bones.  With snake, it is very easy, for example, to put a chunk into your mouth and suck off the meat.  With some other meats you have to be careful not to bite into an unexpected bone and break a tooth.  Fish, to me, is the most dangerous.  In fact, the first time I ordered fish, it was chopped into little pieces, breaded and fried, and when I put a piece into my mouth and began to chew I had bones piercing my tongue and the roof of my mouth, unexpectedly.  Since then, I have always been careful.
So, if you visit China, beware of the bones.
